WhenMichael Scottdiscovered that ex - girlfriend Jan Levinson was wait a baby during the season 4 finale ofThe Office , she like a shot hit him with another jarring revelation : he was not the Fatherhood , though it ’s obvious she had become pregnant while they were still together . or else , she had visited a sperm depository financial institution .

Since we never found out who the sperm donor was , viewers came up with their owntheories . Somethoughtthe sperm banking concern chronicle was a cover - up , and that Jan ’s former assistant Hunter Raymond was the real father . After a delete scene from season 5revealedthatKevin Malonehad donated sperm to that very spermatozoan bank , fan point fingers at him or else .

As UPROXXreports , neither theory is true . On a recentepisodeof herOffice Ladiespodcast with carbon monoxide gas - star Jenna Fischer ( who playedPam Beesly ) , Angela Kinsey ( Angela Martinon the show ) shared that the sperm conferrer ’s identity was originally written into the setting .

Melora Hardin and Steve Carell in 2006.

“ Jan enunciate , ‘ You have to pay top dollar , but it ’s worth it . Now , here ’s the best part . I got Andy Roddick ’s sperm , ’ ” Kinsey said . “ And Michael says , ‘ The lawn tennis player ? ’ And Jan says , ‘ Well , it ’s a little more than that . He ’s the sixth - ranked player in the reality and he ’s succeed four exalted slam . ’ And Michael pronounce , ‘ That ’s a raft of grand slams , I gauge . ’ ”

As for why the lawn tennis star got a yell - out , Fischer has a possibility . She explained on the podcast that Roddick was a big fan ofThe Office , and that he also bump to be champion withRainn Wilson(Dwight Schrute ) . He even stopped by the set at some point . “ I have to imagine that the reasonableness they write it as being Andy Roddick ’s sperm was a small bit of a nod to Andy , who has an amazing good sense of humor , ” she said .

For whatever reason , that flake of dialogue did n’t make it into the scene , robbing us of the opening that Roddick himself would , at some point , turn up on the show .
